Bucket 7 12v micro fans installed in upper helm in hopes they will move air through vents at top (no real faith in this but won't be able to attempt it later so why not) it does blow quite a bit against my forehead when the mask front was attached so it might help evaporate the sweat at least. 12v blowers will also be added in front of Snout to bring air in, may also help disguise voice a bit.
